Annular Cavity Design for Photoluminescent Polymer Optical Fiber Sensors [PDF]

open access: yesSensors, 2020
We present optimization results on the design of a polymer optical fiber single point sensor suitable for photoluminescence-based sensing. The single point sensing design consists of one or two annular cavities, separated by a small distance, milled into

150 MHz polymer resonator for optoacoustic mesoscopy based on a tapered optical fiber [PDF]

open access: yesNature Communications
Optical ultrasound detection enables greater miniaturization than conventional piezoelectric transducers while preserving high sensitivity. Although sub-micron silicon photonics detectors have been demonstrated, image artifacts caused by surface acoustic

U-Shaped and Surface Functionalized Polymer Optical Fiber Probe for Glucose Detection [PDF]

open access: yesSensors, 2017
In this work we show an optical fiber evanescent wave absorption probe for glucose detection in different physiological media. High selectivity is achieved by functionalizing the surface of an only-core poly(methyl methacrylate) (PMMA) polymer optical ...

Isolated sensor networks for high-voltage environments using a single polymer optical fiber and LEDs for remote powering as well as data transmission [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2018
Many applications in high voltage or explosive environments require sensors which are electrically isolated from other components of a system. These sensors need remote powering as well as wireless or isolated data transmission links.
